The DES mode guides the aircraft down at –1000 fpm whilst in the holding pattern until reaching the cleared altitude or altitude constraint.
When in the holding pattern, LAST EXIT UTC/FUEL information is displayed on the MCDU HOLD page. These predictions are based upon the fuel policy requirements specified on the MCDU FUEL PRED page with no extra fuel, assuming the aircraft will divert.
The crew should be aware that this information is computed with defined assumptions e.g.:
? Aircraft weight being equal to landing weight at primary destination
? Flight at FL 220 if distance to ALTN is less than 200 nm, otherwise FL 310 performed at maximum range speed
? Constant wind (as entered in alternate field of the DES WIND page).
 
NORMAL OPERATIONS
HOLDING
 
? Constant delta ISA (equal to delta ISA at primary destination)
? Airway distance for a company route, otherwise direct distance.
Alternate airport may be modified using the MCDU ALTN airport page which can be accessed by a lateral revision at destination.
To exit the holding pattern, the crew should select either:
? IMM EXIT (The aircraft will return immediately to the hold fix, exit the holding pattern and resume its navigation) or
? HDG if radar vectors or
? DIR TO if cleared to a waypoint.

APPROACH GENERAL
 
PREFACE
Applicable to: ALL
This section covers general information applicable to all approach types. Techniques, which apply to specific approach types, will be covered in dedicated chapters.
All approaches are divided into three parts (initial, intermediate and final) where various drills have to be achieved regardless of the approach type.
the approach parts and associated actions
 
INITIAL APPROACH
Applicable to: ALL
NAVIGATION ACCURACY
Prior to any approach, a navigation accuracy check is to be carried out. On aircraft equipped with
GPS however, no navigation accuracy check is required as long as GPS PRIMARY is available. Without GPS PRIMARY or if no GPS is installed, navigation accuracy check has to be carried out. The navigation accuracy determines which AP modes the crew should use and the type of display to be shown on the ND.
THE FLYING REFERENCE
It is recommended to use the FD bars for ILS approaches and the FPV called "bird”" with FPD for non-precision or circling approach approaches.
APPROACH PHASE ACTIVATION
Activation of the approach phase will initiate a deceleration towards VAPP or the speed constraint inserted at FAF, whichever applies.
 
NORMAL OPERATIONS
APPROACH GENERAL
 
When in NAV mode with managed speed, the approach phase activates automatically when
sequencing the deceleration pseudo-waypoint. If an early deceleration is required, the approach phase can be activated on the MCDU PERF APPR page. When the approach phase is activated, the magenta target speed becomes VAPP.
